#176

Describe the solution you'd like
A hotkey that toggles the state of the server in the whitelist. Upon toggling, an actionbar or toast message should confirm the result.

Describe alternatives you've considered
The current situation is an alternative.

Additional context
I don't know how many "free" buttons controllers usually have. It may also be a combination of buttons, though I don't know if your controller editing screen allows combinations. If not, maybe just add a default-added option for the radial menu?
